A cutting blade with multiple body inserts, each comprising a load-sharing member and a flexible perimeter joint. These inserts reduce the magnitude of frictional forces acting on the blade's body. The load-sharing member, in particular, acts as a point contact between the material being cut, such as bone, and the cutting blade. As such, the frictional forces exerted act only on the load-sharing member as opposed to the entire body. By limiting the real contact area, the magnitude of friction generated during operation is reduced. Additionally, the load-sharing members create a thermally insulating space between the body and the material being cut. The functionality of these body inserts, however, relies on the flexible perimeter joint. The flexible perimeter joint isolates the effects of frictional forces to the load-sharing member by preventing direct contact between the load-sharing member and the surrounding body.
